Do NOT root your device unless you find a specific app that tells you you NEED to be rooted. For the most part, those will be apps like keyboards, system tweaks, and things most of us don't need on stock anyway. There's always alternatives to everything, so just look around.

Or you want to look around... as long as you use an app like ChainSDD's SuperUser to control su (root) access, you aren't really increasing your risk.

Or unless you want to poke in and tweak it yourself. Or you want to edit a game save file to "cheat".

Most people won't benefit at all from rooting, but it's not as if rooting it opens it up for automatic destruction.
